how do I avoid buffer underrun?
I'm trying to write a dual-layer blu-ray using the schily cdrecord

I used to use the same method as you, for CDs and DVDs, since the GUI tools misbehaved os badly until recently. Now though, I am happy to use Brasero most of the time with Debian GNU/linux. I can create an ISO image that's 38,961,047,552 bytes, which should fit on a 50G dual-layer blu-ray disk. I am having trouble writing the image onto the disk. I get a message about buffer underruns, and need some help fixing this.

Prerecorded disk? /../ Hmmm, I don't know, but would you try with Brasero for example, and see what the Brasero logs tell you. So many options with the commands possible, hard for me to say if something needs to be changed.... -- Gernot Hassenpflug |

I'm actually using the same blu-ray writer as you and the writer will
write 4X and 6X blanks at 12X speed with ease with the write speed set to maximum. Your buffer underuns are because your Pioneer writer it connected to the usb 2.0 port. You can only burn a DVD-+R at around 8 times speed and that speed would be too slow for burring a BD-R so you need to install the Pioneer writer internally and use UDF 2.5 and something that always works for software. I mostly use TMPGEnc Authoring Works 4.

how do I avoid buffer underrun?
Now that i read all youir **** maybe you need DVDFab but sometimes the
main movie is broken into two parts (especially with 3D movies) instead of one and unless you use clone instead of copy it will only pick up the first part of the MPEG-TS video file.
